Reliable Tankless Water Heaters Services

At On Time Experts, our technicians are experts when it comes to installing and repairing tankless water heaters. If your tankless water heater isn’t functioning as it should, you may notice signs such as a sudden drop in water pressure or cold running water when you turn on the faucet. Another telltale sign of a malfunctioning tankless water heater is unusual behavior from your home’s other hot water appliances, such as the dishwasher or washing machine.
Some common issues that can cause your water heater to suddenly stop working include sediment build-up in the hot water lines and inside of the unit, ignition failures and flame failures. Whatever the underlying problem may be, you can count on our professional technicians to accurately assess the situation and perform all necessary repairs to ensure your water heater runs smoothly again.
Here are some more signs that can indicate a potential issue with your tankless hot water heater:
- Discolored or gritty water
- Unusual sounds during the water heating process
- Complete lack of hot water
- Tap water has an unusual odor
In the event that your tankless hot water heater needs replacing, or if you’re considering swapping out your traditional hot water heater for a tankless model, we can help. We carry and install both electric and gas-powered tankless water heaters, and every water heater we install comes with a warranty of up to 10 years. With proper maintenance, gas and electric tankless water heater systems can last as long as 25 years, and they require less maintenance than traditional tank water heaters.




















Common Tankless Water Heater Problems and Solutions

At On Time Experts, we handle all issues related to tankless water heaters. Here are some common problems and the solutions we provide:
- Sudden Drop in Water Pressure: This could indicate sediment build-up in the hot water lines. Our technicians will flush the lines and clear the sediment to restore normal water flow.
- Cold Water Instead of Hot: Ignition or flame failure may be causing this issue. We’ll assess and repair the ignition system to get your heater functioning again.
- Discolored or Gritty Water: This is often caused by sediment in the heater. We’ll flush the system and clean the water lines to fix this problem.
- Unusual Sounds During Heating: Strange noises can indicate internal issues like sediment buildup. We’ll inspect and service your heater to eliminate the noise.
- No Hot Water: A complete lack of hot water may signal a more significant malfunction, like a failed heating element. We’ll troubleshoot and repair or replace components as needed.

Thinking about making the switch to a tankless water heater?

Our experienced plumbers will evaluate your needs, explain your options, and help you choose a tankless water heater that delivers reliable performance without unnecessary expenses.

Frequently asked questions
Have questions? We're here to help. Explore the frequently asked questions below to learn more about our services, what to expect when you schedule an appointment, and how On Time Experts Heating, Air & Plumbing can help keep your home safe, comfortable, and running smoothly.
In Texas, anyone paid to install a tankless water heater must be a licensed plumber or work under one, though homeowners may do plumbing on their own homestead. The City of Dallas still requires a homeowner to get a permit and a city sign-off when the building code calls for one, and other North Texas cities set their own rules.
A tankless install usually involves gas piping, venting and sizing the unit to your home's demand, which is why most homeowners hire a licensed plumber for it.
Most tankless water heaters should be flushed about once a year, which is the main part of tankless water heater maintenance. Flushing, also called descaling, runs a cleaning solution through the heat exchanger, the part that heats water as it passes through, to dissolve mineral scale.
Many North Texas cities have moderately hard water. Scale makes the heater work harder and can cause error codes or swings in water temperature, so check your owner's manual for your model's schedule.
Replacing a tank water heater with a tankless one is worth it for many households, especially ones that run out of hot water. A tankless unit heats water only when a tap is open, so nothing sits in a tank losing heat, and it often lasts 20 years or more compared with about 10 to 15 for a tank.
The downsides are a higher upfront cost and, in some homes, a larger gas line or new venting. On Time Experts Heating, Air & Plumbing can tell you whether the switch makes sense or a new tank water heater fits better.
A gas tankless water heater is usually the better choice for a whole house that already has gas service, and an electric unit makes more sense for a single bathroom or a home without gas. A gas unit sized for the house can run two or more showers at once, but it needs the right size gas line and proper venting.
Electric whole-house models draw a lot of power and may need an electrical panel upgrade, so the right pick depends on your home's existing gas and electrical service. We install both types.
Tankless water heater installation costs vary with what your home needs to support the new unit. The biggest factors are the size of the unit, whether the gas line has to be upsized, new venting, electrical work for electric models, and where the heater will hang.
Moving from a tank in the garage to a tankless unit on the same wall costs less than relocating it. On Time Experts Heating, Air & Plumbing gives you the price before work starts, and financing is available on approved credit.
